Non Oriented Electromagnetic Steel Sheet, Production Method For Non

Non Oriented Electromagnetic Steel Sheet, Production Method For Non Oriented Electromagnetic Steel Sheet, Electric Motor, And Production Method For Electric Motor

Abstract: The base material of this non-oriented electromagnetic steel sheet has a chemical composition that includes 3.2-4.5 mass% of Si, the tensile strength of the non-oriented electromagnetic steel sheet is at least 550 MPa, and the ratio (P120B/Fe700B)B between the inter-peak height Fe700B for Fe at 700 eV and the inter-peak height P120B for P at 120 eV when the crystal grain boundaries of the non-oriented electromagnetic steel sheet are analyzed by Auger electron spectroscopy is no more than 2.0 times the ratio (P120i/Fe700i)i of the inter-peak height Fe700i for Fe at 700 eV and the inter-peak height P120i for P at 120 eV when the interiors of the crystals of the non-oriented electromagnetic steel sheet are analyzed by Auger electron spectroscopy.
